Answer:

Solutions x= 9 and -9

Step-by-step explanation:

x^2-55=26

x^2=55+26

x^2=81

(take square root of both sides)

x=9

(squaring negatives is the same as squaring the same positive)

x also=-9

Answer:

x= 9 x= -9

Step-by-step explanation:

Equation: x^2-55=26

Move -55 to the other side - x^2=55+26 = X^2 = 81

Solve - x^2=81 - 9^2 = 81 and -9^2=81 (a negative squared becomes a positive)

David is buying a cheese wheel priced at \$650$650dollar sign, 650 before tax. The store charges 8\%8%8, percent sales tax.
lozanna [386]

Answer:

$702

Step-by-step explanation:

To find the total price of the cheese wheel that David is buying, we need to multiply the original cost to sales tax first.

Original Cost = $650

Sales Tax Percentage= 8% or 0.08

Now let's solve for how much the sales tax is.

Sales Tax = 0.08 x 650

Sales Tax = $52

Now to get the price including the tax, we simple add the original cost to the sales tax.

Total Price = $650 + $52

Total Price = $702

So the cheese wheel that David bought is $702 with tax included.

If y = 5x − 4, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?
Mama L [17]

Answer:

x can be any value, x will be the input, y will be the output.

Step-by-step explanation:

If x = 3, If x = 6, If x = 9,

y = 5x - 4

y = 5 (3, 6, or 9) - 4

y = 11, y = 26, y = 41.

These are all possible sets of ordered pairs, but ANY Real number can be represented as X, and it will need to be in an order. These numbers are all positive, so in this case, you just have to draw out Quadrant 1 in a Coor. Plane.

<u>X (Input)  I  Y (Output)</u>

3              I  11

6              I  26

9              I  41

See, when x increases by 3, Y increases by 15. If you go on, it will be the same path, same pattern.

Hope This Helps! :)
